Hydraulic fracturing, or "fracking," produces a lot of wastewater. Drilling one well requires millions of gallons of water that's injected into the ground to loosen rocks and release oil. While some is reused, much of the produced water is discarded into deep injection wells, and clean water is purchased again and again.
